A recent study claims that using music in a class enhances the concentration and con- sequently helps students absorb more information. To figure this out, a school decided to implement it on a smaller group of randomly selected students from two different classes. Two different groups of five randomly selected students (all of the same age) from both classrooms were selected. Each classroom was provided with a different environment for students to study. Classroom A had constant music being played in the background and classroom B was a regular class with no music playing. After one month, the school conducted a test for all the three groups and collected their test scores (out of 10). The obtained test scores were as follows. Class A Class B MC SER Class A Class B 4 5 9587L 6 2 7 At a = 0.05 is there any difference in the mean number of scores obtained from Class A. B?
